I then bent each spike of metal back, resulting in a radiused edge. Cut off the surplus and file away any sharp edges and bob's your uncle. You can enlarge the cut out if necessary with a bit of judicious hammering until it gently clamps the tubing. I put some electrical tape over the cut out and a sleeve over the fuel lines where they pass the firewall.

These connections can be for Metal or armoured tubing. Not a good idea to go through the stainless tin firewall, it's rather bendy, will vibrate and maybe even start to crack. Better to go inside the cabin along the floor from beneath the seat to just behind the rudder pedals, then straight up and through a bulkhead fitting in the roof of the footwell. Now it will be easy to access when you need to change the rubber. This is how Brian Fogg did it, (solid aluminium, even better) and it looks very neat. I just had a week's holiday in the local boneyard, Derby Royal Infirmary, not serious but most uncomfortable. Now I have a crashed desktop and a big pile of emails to sort, so it will be a while before I'm up to speed. If I promised anyone anything please email off list.

Immediately on startup it flickers wildly then as the engine warms up it settles down but to a higher temp. than it was running previously. I have checked the connections and wiring to the sender and all seems OK. I am wondering if :- a) anyone experienced anything similar & if so, what was the cause / outcome. b) anyone who has fitted a digital system has got a VDO gauge they would be prepared to sell.

Graham - never say never ... John Scott at Cambridge told me he has fitted AN taper pins to at least one Europa in place of the original 1/4" parallel pins (TP14A & TP14B). This builder was among the folk who observed that the holes in the torque tube were not very snug on the original pins from day 1, and John's change was made before the torque tube entered service. I certainly felt that my own fairly cautious reaming of the holes for the replacement 3/8" pins (TP14C & TP14D) gave a better fit than the original. John's taper pin approach seems better engineering and I'm not convinced that if correctly fitted they will cause distortion. If I'd heard of it sooner I'd have gone for that myself rather than the 3/8" pins. >Only alternative I can think of is expandinhg pins That also seems quite neat; but how do expanding pins avoid the distortion problem you fear with taper pins? regards Rowland -- | Rowland Carson PFA #16532 | 750 hours building Europa #435 G-ROWI e-mail ________________________________ Message 8 _____________________________________ Time: 03:02:54 PM PST US From: "Jeremy Davey" Subject: RE: Europa-List: torque tube pins [was: no subject] --> Europa-List message posted by: "Jeremy Davey" Rowland, I would certainly agree with you on the 'careful reaming'. I did mine likewise and I hope I never have to get them out because they're tighter than a camel's a**e in a sandstorm! My original 1/4" pins, on the other hand, were rather less so...
